5 Insane Scientific Charts You Won't Believe Actually Exist

Everything needs to measured: Even things you don't want to touch, smell, look at, think about or even exist on the same physical plane as. Because sometimes, you just have to know what precise category of vomit you'd be covered in if you ate too much Subway, or got drunk and played on the merry-go-rounds (Scattershot Olive, is the answer).

Therefore, in some office somewhere, a person is looking at a chart displaying...

#5. The Bristol Stool Scale

What Does it Measure?

It ain't bar chairs. The average person may not be too discerning about their poop, but healthcare professionals, much to their chagrin, need to know a lot about the human body's various excretions. Thus the Bristol Stool Scale was created. You've heard of taking a number two, but it turns out you can actually take a number one through seven.

Thanks for ruining another of life's little pleasures, Science.

And now that you've seen that graphic, you can handily describe all of your poops--from rabbit to flash food--to your horrified, regretful conversational partners. The chart was designed by the University of Bristol and the Scandinavian Journal of Gastroenterology, and the only thing that the chart makes clearer is that there is very little to do in Scandinavia and we don't ever want to go to Bristol.

There's a reason that water is brown.

It's like they're actively trying to be gross. Seriously, read the description for number three again. "Like a sausage, but with cracks." Just really savor those words put together in that order.

...Savory?

Dang. We really liked sausage, too.

#4. Kinsey Scale

What Does it Measure?

The Kinsey Scale measures exactly how gay or straight you are. You may think this seems a bit counter-intuitive at first: either you do dudes or you do not do dudes (Dr. Seuss would be proud). Ah, but if you believe that, you're precisely the type of person who needs the scale.

After all, a quick look at Craigslist will turn up half a dozen ads reading something along the lines of "come over and jerk off on my pecs, but no gay stuff." Obviously, it's not quite so straight-forward.

In fact, "straight" is less than 15 percent of the story.

The scale goes from zero (so heterosexual you can impregnate women over the phone) to six (The Literal Gay Lord, savage emperor of the Gays). A bisexual who is equally attracted to either sex is known as a three, or more colloquially as a "drunk college girl."

We've got no clue where to put Devine.

Alfred Kinsey wasn't winging it when he developed his scale either. It might look like he just slapped numbers on some bathroom signs and called it a day, he did quite a bit of, ahem, grunt work. Kinsey developed his scale not only through interviews, but also observation and active participation in sexual activities, both hetero and homosexual. He even went so far as to film sexual acts between co-workers in his attic.

...for science. Totally for science. Yes. And now science wants you to dress up like a school teacher and show Dr. Kinsey how bad he's been.

#3. Sperm Motility Grade

What Does it Measure?

In courting a new potential mate, there comes a point at every date where you simply have nothing more to talk about. If you're a man, rather than sitting there in uncomfortable silence, now you can impress her with your in-depth knowledge of the Sperm Motility Grade scale!

It not only rates how effective your littlest troops are, but describes in specific detail exactly how they're going to storm her beaches. And if you're a woman, try quizzing him on his semen! Trust us: Asking a dude how well his littlest gentlemen get to work is a sure fire turn on.

"...And they each have a diamond-tipped drilling apparatus and NOS afterburners."

It's fairly straight forward: At the top of the class you have the eye-on-the-prize straight-line swimmers, somewhere in the middle are the drunk drivers, while at the bottom you have one slacker, a midget and a Sharktopus.

But perhaps even more strangely, according to the Sperm Motility Grade scale, the guys on Grade 2 may actually move backwards. It's one thing to not make the commute--we understand and sympathize with laziness--but when your sperm are actively fleeing the vagina, perhaps it's time for drastic measures. There's no shame in bringing your own funnel, gentlemen.
